preflightPre-deploy verification gate. Checks git status, build, tests, migrations, secrets, and commit conventions. Reports READY or NOT READY. Read-only, no changes. Trigger words: preflight, pre-deploy check, ready to deploy, deployment checklist.17 installsdebugSystematic debugging agent — reproduce the issue, isolate the root cause, trace the code path, fix it, and add a regression test. Works with any stack.9 installsbroken-linksScan a codebase for broken links — dead URLs in Markdown/HTML, broken file references, invalid import paths, stale anchor links, and broken cross-doc references — then auto-fix what it can: replace dead URLs with Wayback Machine archives, update moved file paths via git history, remove anchors that no longer exist, and flag what needs human review. Self-healing: learns fix patterns and improves over iterations. Use when: 'fix broken links', 'check links', 'dead links', 'broken urls', 'link rot', 'fix references', 'validate links', 'stale links', 'broken imports'.7 installsautomated-code-quality-analysisA comprehensive, automated code quality analysis tool that performs static analysis across multiple programming languages, identifies issues, security vulnerabilities, code smells, and duplications, and generates detailed, actionable reports to improve code \6 installscode-smellScan codebase for Martin Fowler's catalog of code smells: god classes, long methods, feature envy, data clumps, primitive obsession, shotgun surgery, message chains, and more. Reports each smell with file location, severity, and specific refactoring recommendation. Ranks worst files and builds a prioritized refactoring queue. Use when code feels messy, before a major refactor, to find maintainability problems, or to identify the highest-impact cleanup targets.5 installserror-handlingAdd comprehensive error handling — try/catch, error boundaries, retry logic, user-facing error messages, and graceful degradation across the entire stack.2 installs

Frequently asked questions about data-validation

What does the data-validation skill do?

Add input validation across the stack — request body schemas, query parameter checks, environment variable validation, database constraints, and output sanitization at every entry point. It's a reusable SKILL.md instruction set that loads into your AI coding assistant on demand, no prompt engineering, no copy-pasting every session.

How do I install the data-validation skill?

Run `npx @skills-hub-ai/cli install data-validation` from your terminal. The CLI writes the SKILL.md to the correct location for your AI tool (e.g. ~/.claude/skills/data-validation/ for Claude Code or ~/.cursor/skills/ for Cursor with --target cursor) and adds it to your project's .skills.json lockfile.

Which AI tools does data-validation work with?

data-validation runs in Claude Code, Cursor, Codex CLI. It follows the open Agent Skills standard (SKILL.md), so the same skill works in every supported tool without modification.

Is the data-validation skill free?

Yes. Every skill on skills-hub.ai is free and open-source. There are no premium tiers, paywalls, or usage limits. You only pay for whatever AI assistant you're already using.

How do I use data-validation after installing it?

In Claude Code, type `/data-validation` (or whatever slash command the skill registers) and the AI follows the skill's instructions immediately. You can also reference it by name in natural language, your AI loads the skill into context when relevant.

Can I share the data-validation skill with my team?

Yes. Commit your project's .skills.json lockfile and teammates run `npx @skills-hub-ai/cli install` (no args) to install every skill at the exact version you pinned. Organization-scoped installs work via skills-hub.ai organizations.
